NPK Analysis
Meaning of NPK
They indicate the percentages of the three primary plant nutrients in Reiziger Root Booster. This ratio has been found to be an excellent formula for all short cycle strains of fruiting and flowering plants.
NITROGEN: Nitrogen (N) is a major element in plant nutrition, promoting rapid growth, leaf formation and green colouring.
AVAILABLE PHOSPHATE: Available Phosphate is the source of Phosphorus (P) which is essential for a strong root system, heavier more potent flowers and overall growth. It also hastens maturity plus increases yield and vitamin content in plants.
SOLUBLE POTASH: Soluble Potash is the source of Potassium (K) which is a catalyst for many plant functions. It helps form strong stems, improves colour, provides starches and oils and reduces water needs. Potassium is essential for cell division and balances the effects of excess nitrogen and calcium.

Revival & Survival.
Packed with oligosaccharides renowned for regulating plant growth and boosting protection against damage, Reiziger Root Booster revitalises stressed plants affected by transplant shock, overwatering, underwatering, root sickness, mould, root burn, over-fertilisation, root pruning, or re-potting. Turn to Reiziger Root Booster for an instant boost of explosive new growth, saving you precious weeks of cultivation time. -
Balanced Vitality.
Oligosaccharides offer a dual benefit to plants by promoting growth both above and below ground. Above ground, they support the growth of leaves, stems, and flowers, contributing to the overall vitality of the plant. Below ground, they enhance root development, which is crucial for the plant’s ability to absorb water and nutrients. Plants grow stronger and become more resilient to environmental stressors.
-
Faster seed germination.
There are various effective methods for germinating seeds, but one of the most beneficial is soaking them in Reiziger Root Booster before planting. This process helps to soften the seed coat, allowing the emerging plant to sprout more easily and ensuring a healthier, more robust start to its growth journey. -
Frost protection.
Enhances and accelerates the acclimatisation process, even when the plant is not experiencing cold stress. This improved resilience allows the plant to withstand lower temperatures more effectively, reducing potential damage and promoting continued healthy growth in cooler conditions.
DIRECTIONS
For spectacular results, feed it right.
The beauty of Reiziger Root Booster for your plants is that you can feed as you water. For a profusion of roots and blooms, feed all of your plants this crystal clear liquid using all fertigation systems – drip systems, sprinklers, centre pivots and spray units.

Mix 1 mL in 1L water and drench, dip, irrigate or foliar spray 1 – 6 times daily for the first few weeks until roots appear, or plant is strong. Decrease to 0.5 mL in 1L after healthy roots are established. Add to fertiliser program or apply when plants are thirsty by drenching or irrigating.

Mix 0.25 mL in 1L water. Add to fertiliser program or apply when plants are thirsty by drenching or irrigating.
MEASURING TECH
How to measure.
The innovative dosing system is the first closed liquid dosing system in the
world and enables the user to dose a specific amount of liquid in only three steps.
No longer is it necessary to orientate the packaging or squeeze the reservoir.
Overdosing or over-pouring are now a thing of the past.
